There are certain things to be aware of when making API calls and when calling external functions from a DLL including:

- Care must be taken when calling APIs and DLLs because it is possible to cause Windows or Liberty BASIC to become unstable or crash if API and/or DLL functions are called incorrectly, out of order, or with incorrect parameter information.

- Shoptalk Systems does not provide technical support for the Windows API or for third party DLLs that that may be purchased or otherwise obtained. We are happy to help you with any questions about Liberty BASIC commands and features that are related to calling APIs and DLLs, but we reserve the right to refuse to answer questions about other products (including Windows).
